THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Features

See the Catalyst 3560 Switch Getting Started Guide for instructions on how to use Express Setup to initially configure your Catalyst switch. The getting started guide provides switch management options, basic rack-mounting procedures, port and module connections, power connection procedures, and troubleshooting help.

For instructions on setting up your switch using the command-line interface (CLI), see Appendix D,

“Configuring the Switch with the CLI-Based Setup Program.”

The 24- and 48-port Catalyst 3560 switches can be deployed as backbone switches, aggregating 10BASE-T and 100BASE-TX Ethernet traffic from other network devices. The Catalyst 3560-8PC and the Catalyst 3560-12PC-S compact switches provide the same Power over Ethernet (PoE) connectivity and can be deployed outside the traditional wiring closet environment, such as in office workspaces and classrooms. The switches are hot-swappable. See the switch software configuration guide for examples of how you might deploy the switch.

For power redundancy, all but the Catalyst 3560 8- and 12-port switches include connections for an optional Cisco RPS 2300 or Cisco RPS 675 that operates on AC power and supplies backup DC power to the switches.

Chapter 1 Product Overview

The 10/100/1000 ports on the Catalyst 3560G-48TS switch are grouped in pairs. The first member of the pair (port 1) is above the second member (port 2) on the left, as shown in Figure 1-10. Port 3 is above port 4, and so on. The SFP module slots are numbered 49 to 52.

Figure 1-10 Catalyst 3560G-48TS Switch Front Panel

1 10/100/1000 ports 2 SFP module slots

10/100 and 10/100/1000 Ports

• You can set the 10/100 ports to operate in any combination of half duplex, full duplex, 10 Mb/s, or

100 Mb/s. You can set the 10/100/1000 ports to operate at 10 or 100 Mb/s in half or full duplex or at 1000 Mb/s in full duplex.

• You can set both the 10/100 and the 10/100/1000 ports for speed and duplex autonegotiation, in

compliance with IEEE 802.3ab. (The default setting is autonegotiate.)

• You can configure duplex mode to half, full, or autonegotiate on Gigabit Ethernet interfaces if the

speed is set to 10 or 100 Mb/s. You cannot configure half-duplex mode on Gigabit Ethernet interfaces if the interface speed is 1000 Mb/s.

• When set for autonegotiation, the port senses the speed and duplex settings of the attached device

and advertises its own capabilities. If the connected device also supports autonegotiation, the switch port negotiates the best connection (the fastest line speed that both devices support and full-duplex transmission if the attached device supports it) and configures itself accordingly. In all cases, the attached device must be within 328 feet (100 meters).

Warning

Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection methods, unless the exposed metal parts are located within a restricted access location and users and service people who are authorized within the restricted access location are made aware of the hazard. A restricted access area can be accessed only through the use of a special tool, lock and key or other means of security.

Statement 1072

• 100BASE-TX and 1000BASE-T traffic requires Category 5 cable. 10BASE-T traffic can use

Category 3 or Category 4 cables.

Chapter 1 Product Overview

PoE Ports

Front Panel Description

• When you connect the switch to workstations, servers, routers, and Cisco IP Phones, be sure that the

cable is a straight-through cable. When you connect the switch to switches or hubs, use a crossover cable. When using a straight-through or crossover cable for 1000BASE-T connections, be sure to use a twisted four-pair, Category 5 cable for proper operation. Pinouts for the cables are described in Appendix B, “Connector and Cable Specifications.”

• You can use the mdix auto interface configuration command to enable the automatic

medium-dependent interface crossover (auto-MDIX) feature. When the feature is enabled, the switch detects the required cable type for copper Ethernet connections and configures the interfaces accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to a copper 10/100, 10/100/1000, or 1000BASE-T SFP module port on the switch, regardless of the type of device on the other end of the connection.

The auto-MDIX feature is enabled by default on switches running Cisco IOS Release 12.2(18)SE or later. For releases between Cisco IOS Release 12.1(14)EA1 and 12.2(18)SE, the auto-MDIX feature is disabled by default. For configuration information for this feature, see the switch software configuration guide or the switch command reference.

• The10/100 and 10/100/1000 PoE ports on the switch provide PoE support for devices compliant

with IEEE 802.3af and Cisco prestandard PoE support for Cisco IP Phones and Cisco Aironet Access Points.

• Each of the Catalyst 3560-8PC, 3560-12PC-S, 3560-24PS, and 3560V2-24PS switch 10/100 ports

or the Catalyst 3560G-24PS switch 10/100/1000 ports deliver up to 15.4 W of PoE.

On the Catalyst 3560-48PS, 3560G-48PS, and 3560V2-48PS switches, any 24 of the 48 10/100 or 10/100/1000 ports delivers 15.4 W of PoE, or any combination of the ports delivers an average of

7.7 W of PoE at the same time, up to a maximum power output of 370 W.

The Catalyst 3560-12PC-S switch delivers a maximum power output of approximately 125 W total PoE power.

• On a per-port basis, you can control whether or not a PoE port automatically provides power when

an IP phone or an access point is connected. The device manager, Network Assistant, and the CLI provide PoE settings for each 10/100 or 10/100/1000 PoE port:

–

Auto: When you select the Auto setting, the port provides power only if a valid powered device, such as an IEEE 802.3af-compliant powered device, a Cisco prestandard IP phone, or a Cisco prestandard Cisco access point, is connected. The Auto setting is the default.

–

Never: When you select the Never setting, the port does not provide power even if a Cisco IP phone or an access point is connected.

• You can connect a Cisco IP Phone or Cisco Aironet Access Point to a Catalyst 3560 PoE switch

10/100 or 10/100/1000 port and to an AC power source for redundant power. The powered device might change to the AC power source as its primary power source when connected to it. In that case, the PoE port becomes the backup power source for the powered device.

OL-6337-07

If the primary source fails, the second power source becomes the primary power source to the powered device. During the power transfer, an IP phone might reboot or reestablish link with the switch.

For information about configuring and monitoring PoE ports, see the switch software configuration guide. For information about Cisco IP Phones and Cisco Aironet Access Points, see the documentation that came with your IP phone or access point.

Catalyst 3560 Switch Hardware Installation Guide

Many legacy powered devices, including older Cisco IP phones and access points that do not fully support IEEE 802.3af, might not support PoE when connected to the switches by a crossover cable.

SFP Module Slots

See the release notes for the latest list of supported SFP modules.

SFP Modules

The switch uses Gigabit Ethernet SFP modules to establish fiber-optic and 1000BASE-T connections. These transceiver modules are field-replaceable, providing uplink interfaces when inserted in an SFP module slot. Use fiber-optic cables with LC or MT-RJ connectors to connect to a fiber-optic SFP module. Use a Category 5 cable with RJ-45 connectors to connect to a copper SFP module.

For more information about SFP modules, see your SFP module documentation or the release note for your switch software.

SFP Module Patch Cable

Chapter 1 Product Overview

The switch supports the SFP module patch cable (CAB-SFP-50CM=), a 0.5 meter, copper, passive cable with SFP module connectors at each end (see Figure 1-11).

Figure 1-11 SFP Module Patch Cable

The SFP module patch cable can connect only two Catalyst 3560 switches. To connect a Catalyst 3560 switch to other Catalyst series switches, you must use the SFP modules specified in the

“SFP Module Cable Specifications” section on page B-4.

See “Inserting and Removing the SFP Module Patch Cable” section on page 2-18 for more information about using the SFP module patch cable.

Dual-Purpose Port

You can configure a dual-purpose port as either a 10/100/1000 port or as an SFP module port. Each port is considered as a single interface with dual front ends—an RJ-45 connector and an SFP module connector. The dual front ends are not redundant interfaces. The switch activates only one connector of the pair at a time.

By default, the switch dynamically selects the interface type that first links up. However, you can use the media-type interface configuration command to select the RJ-45 connector or the SFP module connector. For information about configuring speed and duplex settings for a dual-purpose uplink, see the software configuration guide.

Each uplink port has two LEDs. One shows the status of the RJ-45 port, and one shows the status of the SFP module port. The port LED is on for the active connector.

The Cisco RPS 2300 is a redundant power system that supports six network switches and provides power to one or two failed switches at a time. It automatically senses when the internal power supply of a connected switch fails and provides power to the failed switch, preventing loss of network traffic.

The Cisco RPS 2300 has two output levels: -52 V and 12 V. The maximum output power depends on the installed power-supply modules.

The Cisco 675 RPS is a redundant power system that supports six network devices and provides power to one failed switch at a time. It automatically senses when the internal power supply of a connected switch fails and provides power to the failed switch, preventing loss of network traffic.

The Cisco RPS 675 has two output levels: –48 V and 12 V. The maximum output power is 675 W.

You can connect the switch to a PC by means of the console port and the supplied RJ-45-to-DB-9 female cable. If you want to connect the switch console port to a terminal, you need to provide an RJ-45-to-DB-25 female DTE adapter. You can order a kit (part number ACS-DSBUASYN=) containing that adapter from Cisco. For console port and adapter pinout information, see the “Connector and Cable

Warnings

Chapter 2 Switch Installation (24- and 48-Port Switches)

These warnings are translated into several languages in the Regulatory Compliance and Safety Information for the Catalyst 3560 Switch.

Warning

To prevent the switch from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 113•F (45•C). To prevent airflow restriction, allow at least 3 inches (7.6 cm) of clearance around the ventilation openings.

Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.

Do not stack the chassis on any other equipment. If the chassis falls, it can cause severe bodily injury and equipment damage.

An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure that no exposed portion of the DC-input power source wire extends from the terminal block plug.

Statement 122

Blank faceplates (filler panels) serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards and faceplates are in place.

Preparing for Installation

Note The grounding architecture of this product is DC-isolated (DC-I).

Installation Guidelines

When you determine where to place the switch, be sure to observe these requirements:

• The operating environment is within the ranges listed in Appendix A, “Technical Specifications.”

• Airflow around the switch and through the vents is unrestricted.

• Clearance to front and rear panels meets these conditions:

–

You can easily read the front-panel indicators.

–

Access to ports is sufficient for unrestricted cabling.

–

The rear-panel power connector is within reach of an AC power receptacle.

• Temperature around the unit does not exceed 113°F (45°C).

If the switch is installed in a closed or multirack assembly, the temperature around it might be greater than normal room temperature.

• Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent

lighting fixtures. Make sure the cabling is safely away from other devices that might damage the cables.

• For copper Ethernet ports, including 10/100 ports, 10/100/1000 ports, and 1000BASE-T SFP

module ports, cable lengths from the switch to connected devices can be up to 328 feet (100 meters).

OL-6337-07

• The cables meet the specifications in Table B-1 on page B-4, which lists the cable specifications for

1000BASE-X and 100BASE-X SFP modules for the Catalyst 3560 switch. Catalyst 3560 switch SFP ports use both GLC-GE-100XX and GLC-FE-100XX SFP modules.

When you use shorter lengths of single-mode fiber cable, you might need to insert an inline optical attenuator in the link to avoid overloading the receiver.

Catalyst 3560 Switch Hardware Installation Guide

2-5

Verifying Switch Operation

• Cisco Ethernet Switches are equipped with cooling mechanisms, such as fans and blowers.

Chapter 2 Switch Installation (24- and 48-Port Switches)

When the fiber-optic cable span is less than 15.43 miles (25 km), you should insert a 5-decibel (dB) or 10-dB inline optical attenuator between the fiber-optic cable plant and the receiving port on the 1000BASE-ZX SFP module at each end of the link.

However, these fans and blowers can draw dust and other particles, causing contaminant buildup inside the chassis, which can result in a system malfunction.

You must install this equipment in an environment as free as possible from dust and foreign conductive material (such as metal flakes from construction activities).

These standards provide guidelines for acceptable working environments and acceptable levels of suspended particulate matter:

–

Network Equipment Building Systems (NEBS) GR-63-CORE

–

National Electrical Manufacturers Association (NEMA) Type 1

–

International Electrotechnical Commission (IEC) IP-20

This applies to all Cisco Ethernet switches except for this compact model:

–

Catalyst 3560-8PC switch—8 10/100 PoE ports and 1 dual-purpose port (one 10/100/1000BASE-T copper port and one SFP module slot)

Box Contents

The switch getting started guide on Cisco.com describes the box contents. If any item is missing or damaged, contact your Cisco representative or reseller for support.

Tools and Equipment

You need to supply a number-2 Phillips screwdriver to rack-mount the switch.

Verifying Switch Operation

Before you install the switch in a rack, on a wall, or on a table or shelf, you should power the switch and verify that the switch passes POST. See Section 3, “Running Express Setup,” in the getting started guide for the steps required to connect a PC to the switch and to run Express Setup.

If your configuration has an RPS, connect the switch and the RPS to the same AC power source. See the

“Cisco RPS” section on page 1-19, and see the Cisco RPS documentation for more information.

Note When you connect the RPS to the switch, put the RPS in standby mode. Set the RPS to active mode

during normal operation.

2-6

To power on the switch, connect one end of the AC power cord to the AC power connector on the switch, and connect the other end of the power cord to an AC power outlet.

Warning

Catalyst 3560 Switch Hardware Installation Guide

Attach only the following Cisco RPS model to the RPS receptacle: PWR-RPS2300, PWR675-AC-RPS-N1=.

Statement 370

OL-6337-07

Chapter 2 Switch Installation (24- and 48-Port Switches)

As the switch powers on, it begins the POST, a series of tests that runs automatically to ensure that the switch functions properly. LEDs can blink during the test. POST lasts approximately 1 minute. When the switch begins POST, the System, RPS, Status, Duplex, and Speed LEDs turn green. The System LED blinks green, and the other LEDs remain solid green.

When the POST completes successfully, the System LED remains green. The RPS LED remains green for some time and then reflects the switch operating status. The other LEDs turn off and then reflect the switch operating status. If a switch fails POST, the System LED turns amber.

POST failures are usually fatal. Call Cisco technical support representative if your switch fails POST.

Powering Off the Switch

After a successful POST, disconnect the power cord from the switch. Install the switch in a rack, on a wall, on a table, or on a shelf as described in the “Installing the Switch” section on page 2-7.

Table- or Shelf- Mounting

Step 1 Locate the adhesive strip with the rubber feet in the mounting-kit envelope. Attach the four rubber feet

to the bottom of the switch near the corners.

Note Do not attach the rubber feet over the recessed screw holes on the bottom of the switch.

Step 2 Place the switch on the table or shelf near an AC power source.

After the switch is mounted in the rack:

1. Power on the switch. See the “Verifying Switch Operation” section on page 2-6.

2. Connect to a 10/100 or 10/100/1000 port, and run Express Setup. See the Catalyst 3560 Switch

Getting Started Guide for instructions. To use the CLI setup program, see Appendix D,

“Configuring the Switch with the CLI-Based Setup Program.”

3. Connect to the front-panel ports.

Installing and Removing SFP Modules

Note When the connectors are not being used, replace the dust covers on them for protection.

Installing and Removing SFP Modules

The SFP modules are inserted into the SFP module slots on the front and provide uplink interfaces. You can use any combination of SFP modules. See the Catalyst 3560 release notes for the list of supported SFP modules. Each port must match the wave-length specifications on the other end of the cable, and for reliable communications, the cable must not exceed the stipulated cable length. See the Table B-1 on

page B-4 for cable stipulations for SFP connections.

Use only Cisco SFP modules. Each SFP module has an internal serial EEPROM that is encoded with security information, which Cisco uses to identify and validate that the SFP module meets the requirements for the switch.

For detailed instructions on installing, removing, and cabling the SFP module, see the SFP module documentation.

Caution We strongly recommend that you do not install or remove fiber-optic SFP modules with cables attached

because of the potential damage to the cables, the cable connector, or the optical interfaces in the SFP module. Disconnect all cables before removing or installing an SFP module.

Removing and installing an SFP module can shorten its useful life. Do not remove and insert SFP modules more often than is absolutely necessary.

Chapter 2 Switch Installation (24- and 48-Port Switches)

Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis.

Step 2 Find the send (TX) and receive (RX) markings that identify the top side of the SFP module.

Note On some SFP modules, the send and receive (TX and RX) markings might be replaced by arrows

that show the direction of the connection, either send or receive (TX or RX).

Step 3 Align the SFP module in front of the slot opening.

Step 4 Insert the SFP module into the slot until you feel the connector on the module snap into place in the rear

of the slot. (See Figure 2-14.)

Chapter 2 Switch Installation (24- and 48-Port Switches)

10/100 or 10/100/1000 Ports

The switch 10/100 and 10/100/1000 ports configure themselves to operate at the speed of attached devices. If the attached ports do not support autonegotiation, you can explicitly set the speed and duplex parameters. Connecting devices that do not autonegotiate or that have their speed and duplex parameters manually set can reduce performance or result in no linkage.

Note You can configure duplex mode to half, full, or autonegotiate on Gigabit Ethernet interfaces if the speed

is set to 10 or 100 Mb/s. You cannot configure half-duplex mode on Gigabit Ethernet interfaces if the interface speed is 1000 Mb/s.

10/100 or 10/100/1000 Ports

Warning

Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection methods, unless the exposed metal parts are located within a restricted access location and users and service people who are authorized within the restricted access location are made aware of the hazard. A restricted access area can be accessed only through the use of a special tool, lock and key or other means of security.

Statement 1072

To maximize performance, choose one of these methods for configuring the Ethernet ports:

• Let the ports autonegotiate both speed and duplex.

• Set the port speed and duplex parameters on both ends of the connection.

You can configure the 10/100 or 10/100/1000 ports on the Catalyst 3560 PoE switches either to automatically provide PoE if a Cisco IP Phone, Cisco Aironet Access Point, or end device compliant with IEEE 802.3af is connected or to never provide PoE, even if an IP phone or an access point is connected. The default setting is Auto. To prevent electrostatic-discharge (ESD) damage, follow your normal board and component handling procedures.

Caution PoE faults are caused when noncompliant cabling or powered devices are connected to a PoE port. Only

standard-compliant cabling can be used to connect Cisco prestandard IP Phones or wireless access points or IEEE 802.3af-compliant devices to PoE ports. You must remove a cable or device that causes a PoE fault from the network.

You can use the mdix auto interface configuration command in the CLI to enable the automatic medium-dependent interface crossover (auto-MDIX) feature. When the auto-MDIX feature is enabled, the switch detects the required cable type for copper Ethernet connections and configures the interfaces accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to a copper 10/100, 10/100/1000, or 1000BASE-T SFP module port on the switch, regardless of the type of device on the other end of the connection.

The auto-MDIX feature is enabled by default on switches running Cisco IOS Release 12.2(18)SE or later. For releases between Cisco IOS Release 12.1(14)EA1 and 12.2(18)SE, the auto-MDIX feature is disabled by default. For configuration information for this feature, see the switch software configuration guide or the switch command reference.

Connecting the Switch to Compatible Devices

The Catalyst 3560 switch can connect to a Cisco IP Phone through a straight-through, twisted four-pair Category 5 cable. The rear panel of the Cisco IP Phone might have more than one RJ-45 connector. Use the LAN-to-phone connector to connect the IP phone to the switch. See the Cisco IP Phone documentation for more information about connecting devices.

Many legacy powered devices, including older Cisco IP phones and access points that do not fully support IEEE 802.3af, might not support PoE when connected to the switches by a crossover cable.

Connecting the Switch to Compatible Devices

• Connecting to 10BASE-T or 100BASE-TX Devices, page 2-20

• Connecting to Fiber-Optic SFP Modules, page 2-21

• Connecting to 1000BASE-T SFP Modules, page 2-22

• Connecting to a Dual-Purpose Port, page 2-23

Connecting to 10BASE-T or 100BASE-TX Devices

2-20

Step 1 When connecting to workstations, servers, routers, and Cisco IP Phones, connect a straight-through

cable to an RJ-45 connector on the front panel. (See Figure 2-18.) When connecting to switches or repeaters, use a crossover cable. (See the “Cable and Adapter Specifications” section on page B-4 for cable-pinout descriptions.)

Figure 2-18 Connecting to an Ethernet Port

Step 2

Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on when both the switch and the connected device have established link.

The port LED is amber while Spanning Tree Protocol (STP) discovers the topology and searches for loops. This takes about 30 seconds, and then the port LED turns green. If the port LED does not turn on, the device at the other end might not be turned on, or there might be a cable problem or a problem with the adapter installed in the attached device. See Chapter 4, “Troubleshooting,” for solutions to cabling problems.

Note The grounding architecture of this product is DC-isolated (DC-I).

Installation Guidelines

When you determine where to place the switch, be sure to observe these requirements:

• The operating environment is within the ranges listed in Appendix A, “Technical Specifications.”

• Airflow around the switch and through the vents is unrestricted. Allow at least 3 inches (7.6 cm) of

clearance on all sides and ventilation openings, particularly if you stack the switches or place them side by side.

• You have allowed at least 1.75 inches (4 cm) of clearance above each switch in the rack.

• Clearance to front and rear panels is such that

–

You can easily read the front-panel indicators.

–

Access to ports is sufficient for unrestricted cabling.

–

The rear-panel power connector is within reach of an AC power receptacle.

• Temperature around the unit does not exceed 113°F (45°C).

If the switch is installed in a closed environment or in a multirack assembly, the temperature around it might be greater than normal room temperature.

• The heat sinks and the bottom of the switch might be hot to the touch if the switch is operating at

its maximum temperature 113°F (45°C) and is in an environment that exceeds normal room temperature (such as in a closet, in a cabinet, or in a closed or multirack assembly).

OL-6337-07

• No other items are placed on the top of the switch.

• The switch is not wall-mounted with its front panel facing up or sideways. According to safety

regulations, wall-mount the switch with its front panel facing down to prevent airflow restriction and to provide easier access to the cables.
